Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a tail gas treatment structure for a reverberatory furnace. Background Technique

[0002] A reverberatory furnace, also known as a flame reverberatory furnace, is a metallurgical furnace that directly heats materials with flames to smelt metals. It consists of three main parts: a combustion chamber, a smelting chamber, and an exhaust flue (chimney). The entire furnace chamber is a rectangular smelting chamber lined with refractory materials. The reverberatory furnace has a simple structure, low investment, and a wide variety of fuels can be used (such as coal, gas, heavy oil, etc.). It is an important smelting equipment for non-ferrous metals such as copper, nickel, and tin, and is widely used to process ores and concentrates, especially fine-grained powders; it can also smelt ferroalloys and be used for the pyrometallurgical refining of metals. However, due to the direct contact between the flame and the metal, the oxidation loss of the metal is large. Reverberatory furnaces are commonly used as roasting equipment in the fields of metallurgy, chemical engineering, etc.

[0003] Chinese Patent CN217015803U discloses a tail gas treatment structure for a calcination furnace used in gypsum production, which relates to the technical field of calcination furnaces and includes a frame body and a treatment device for treating tail gas. The treatment device includes: a treatment box, which is arranged on the frame body and connected to the calcination furnace; a filter frame, which is arranged on the treatment box and used for filtering particulate impurities in the tail gas; and an absorption plate, which is arranged on the treatment box and used for absorbing toxic gases that have passed through the filter frame. In this application, the filter frame first filters out particulate impurities from the tail gas, and then the absorption plate absorbs the toxic gases. At the same time, the particulate impurities are filtered out first, thereby reducing the probability of the particulate impurities blocking the absorption plate, improving the absorption effect of the absorption plate on the toxic gases and the rate of gas passing through the absorption plate, and thus reducing the pollution of the tail gas to the environment.
